4.1 W Mode Functions
4.1.1 PC Link Function
The PC link function is a communication function that enables data to be shared be-
tween programmable controllers, using cyclically transmitted link relays (L) and link reg-
isters (LD).
In order for the link relay and link register to specify the configuration in which the various
CPUs in the same system are to be used, it is necessary to allocate a link area. Link
area allocations are specified using system registers (
*
Section 4.2).
4.1.2 Data Transfer Function
Data transfer is a communication function by which programmable controllers in the
same system send and receive information pertaining to contacts and registers, using
programs. High - level instructions F145/P145 and F146/P146 are used to exchange
data directly with other CPUs.
For detailed information, refer to the FP series (FP - C/FP2/FP3/FP5/FP10/ FP10S/
FP10SH) programming manual.
4.1.3 Remote Programming Function
With the remote programming function, the same operations can be carried out from
a remote location with respect to programmable controllers in the same system as those
possible when the programming software (NPST - GR) has been connected directly to
the system.
If the programmable controllers are in the same system, which is connected by the link
units, the programming functions of a nearby programmable controller can be used to
program other programmable controllers, and for operations such as monitoring the
various contacts and registers.
